This ‘accordion style’ underlayment was built for speedy installation. Its rigid structure lays flat and has a printed grid on top which makes it easier to lay out and trim to fit a room. SilverStep’s cross-linked (closed cell) foam provides superior protection from both moisture and sound (noise) sources. SilverStep’s extra thick pad provides good thermal insulation properties and makes it especially suited for subfloors with a rougher than normal finish. This underlayment can be used on radiant heat floors.
